Be it known that I, PRnN'rrcE H. BoTToMs,

`citizen of the United States, residing at lllresno`,V in the county ofFresno and State of California,have j invented certain `new and useful Improvements in 4Automatic Vl/Vater-Heater Valves, of which 'the follow- Thslinventionjrelatesto valves and more particnlarlyvto ,valves adapted for use in connection with what` are ainiliarly known instantaneoushot waterheaters.V Broadly speaking, 'in devices of` this character there is provided anjfau'tomatically operating valve contrelled' by the passage of water therewater del'veredwout the spigot is of a desired temperature.

"'QneV of Vthe objects Aof thefpresent'inven-h will 'be inexpensive to manufacture..

which', will be reliable, eilicient and more economical 1n use and operation.

A further object isfto provide a valve of j the above general character, the operation of which may be partially controlled by the manner in which the spigotjis turned on,

thereby to deliver either hot or cold water, as desired. i. p v u .4 a Othervobjectsjwill bein part obvious from the annexedrdrawings and in part indicated v pletely outlined herein.

`Referring now to the drawings in detail,

denotesa member, preferably a brass casting having a relatively large chamber 6 and a smaller chamber 7 at one side thereof. An lnletS Is' provided near the top of the chamber 6. and two outlets l0 and 11 connect the Opposite j. side ofV said chamber with the"A chamber 7. e Within the chamber 6 is a cyj:lindricalpistonV 12 having` a pistonv rod 13 extending downwardly through an opening l in the bottoni,

which opening is provided with amsuitabley packing device 14:, substan-4 reasons, [it is believed to be unnecessary to show the same in detail. These parts are so positioned, and arranged that as the I piston moves downwardly, it will actuate u thememberil and turn on the gas or otherv tionfis yto provide asimple and practical devicelof'theab'ovefgeneral character which adaptedto. register with the inlet 8 in all positions. a At the opposite side of the openopening 18 communicating' with the passage 10 in one positionand the passage 11 in the lower positionY of the piston 12. A spring 20 is provided for holding the piston in its normally raised position,was shown. Theupwardly projecting flange 16 is also provided at one side inter- .mediate the openings 17 and 18 withV an elongatedslot 21 adapted to be engaged by the'end or'a screw 92 threaded into the side wallofthe 'chamber '6 adapted to prevent a a l f rotation of the piston 12 and always main- This invention accordingly consistsin theu features lof construction, combination oitV parts and in the unique relations of the.

taining the openings 1'1" and 18 in proper frthefchamber 6 to permit access thereto Vwhen desired. Thechamber 7 is also `providedwith a piston at one side of which are afpluralityof small openings 26 adapted to register with the passage 10. At the Opposite side are other openings 27 adapted to registerwithv an outlet 2S which leads to the heating coil, not shown, and thence to the 'spigotV This piston'25 is provided` with aj'srn'all vertical opening or cut away pbrtionl lto permit water to now through heinlets Z6 and out through the opening 27 and: nozzlelffto the passage 28 when the spigot is turned very slowly without-caus--D ing any material actuation movement of the i piston 12. The piston 25 is also provided with a short piston rod or guiding membei` 32 about which is coiled a spiral spring 33 resting upon a screw cap 34 at the bottom of the chamber. A slot 35 is also provided in the upper part of the piston 25 engaged by` a set screw 36 threaded into the outer wall fof the chamber 7 to limit the up and downmovement of the piston 2 fand also to prevent relative rotation which would otherwisef carry the openings or ports 26 and 27 out of alinement with the inlet and outlet.

Now, as above explained, one of the objects of the present invention is to provide a valve which will permit a full flow drawing either4 hot or cold water, as desired, accordingto the manner rather than the direction in which the spigot is actuated. If hoti water is desired, the spigot is turned on lquickly which will relieve the pressure in the` system and particularly below the piston 12 and the head of water from the inlet 8 will force this piston downwardly, closing the outlet 10 at the upper part by reason ofthe upwardly extending flange until the opening 18 in the flange registers with `the out-let 11. This permits a clear passage of thewater through the chamber 6 to the heating coilI and spigot.` In the neath the heating coil. a full flow of cold Water is desired, or a small amount of hot water from a previous through the actuation of the device which still remains i to the outlet 28 by means of the notch 31 which does not materially reduce the back pressure beneath the piston 12. There is,

however, sufficient pressure above piston 25 to force it downwardly, thus closing the outlet 11 from the chamber 6 by the lower part4 of the piston. The main opening 26 is then in register with the passage 10, as shown in` dotted lines and the opening 27 will register l with the outlet 28. The spigot may then be 1 turned farther and allow a substantial full. head of water to pass through the device without actuating the piston 12, this being cut off from an eifective back pressure action by the lower part of the piston 25, as above explained.

It will thus be seen that the present device4 will permit the drawing of either hot or cold water as desired and will also inaterially reduce the expense of operation, inasmuch as the gas is not turned on and wasted every time the spigot is turned on.

The construction is simple and practical and inexpensive and is believed to accomplish, among others, all of the objects and advantages herein set forth.

Without further analysis, the foregoing will so fully reveal the gist of this invention that others can by applying current .knowledge readily adapt it for various aplency of the following claims.A

I claim:

1. In a device of the character described,

in combination, a heating means control, va spigot, a plurality of water passages lead- Ving to said spigot through said device and ineans controlled by the turning of said g5 spigot to direct a full flow of water through veither passageway and to actuatethe heating means control or not, as desired.

2. In a device of the character described, i

in combination, a heating means control, a

spigot, two water passages leading to said spigot, and means.controlled by the'` inanner of turning on said .spigot to direct the water through either of saidpassageways to the exclusion of the other and` to actuate f the heating means control or not, ras' desired. meantime, however, the vlower end of the piston rod 13 has actuated the valve lever 15 to turn on the heating means or gas be- If, on the other hand, l

itons ,in said chambers controlled by the turning of said spigot-to direct the water through either chamber to the exclusion of f the other, thereby to actuate thelheating" means control or not, as desired. a 4. In a device of the character described, in combination, a heating means control, a spigot, two water passageways leading to said spigot including chambers and spring J actuated pistons constituting valvesV for closing and opening said passageways, said valves being adapted to be actuated by the manner in which said spigot is actuated to direct the water through either passageway A' and to actuate said heating means control or not, as desired.

5. In a device of the character described, heating means control, a spigot, two water-, passageways leading to said spigotincludf ing separate chambers, flanged pistons with- 1210 in said chambers, springs for holding said pistons in normally raised position, ports in the flanges of said pistons communicatoing with the inlets and outlets. of the pas-l i sages whereby either piston is lactuated according to the manner of turning on the spigot to actuate the heating means control or not, as desired. l w

6. In a device of the character described, d heating means control, a spigot, two water passageways leading to said spigot including separate chambers, ianged pistons Within said chambers, springs for holding said pistons in normally raised position, ports in the flanges of said pistons communicating with the inlets and outlets of the passages, and means associated With the anged pistons adapted to prevent relative rotation thereof with respect to the chambers, Whereby either piston is actuated according to the 10 manner of turning on the spigot to actuate the heating means control or not, as desired. In testimony whereof I affix my signature in presence of two Witnesses.
